In the drama, Ji Sung, regardless of his personality, uses his hand to protect Hwang Jung Eum’s head whenever she is getting into a car, which was dubbed by fans as “manner hands.” The actor explains, “It happened when I was trying to score points with my wife [Lee Bo Young],” and says that the habit just came out when he was filming. “It’s what I did because I didn’t want [Lee Bo Young’s] head to hit the car; I guess you could say it just worked out.”
